Description

Technical Field

[0001] The utility model relates to the technical field of fire alarms, in particular to a liftable fire alarm. Background Art

[0002] With the increase in fire and electricity consumption in modern hotels, restaurants, entertainment venues and homes, the frequency of various fires is getting higher and higher. In order to be able to discover fires early and avoid major losses of life and property, people are now generally equipped with fire alarms. There are many types of existing alarms. From the principle and function point of view, there are mainly ion, photoelectric and temperature sensing types. The alarm uses the highly sensitive detection elements installed inside to capture abnormal changes in temperature and gas content in the air and send out alarm signals. Publication number: CN218671488U discloses a fire alarm, which belongs to the field of fire alarm technology, including a support plate, a mounting plate installed on the upper surface of the support plate, and an alarm body arranged below the support plate. A U-shaped mounting frame is arranged above the mounting plate, and two grooves are provided in the mounting plate. A rotating shaft is rotatably installed in the groove. One end of the rotating shaft extends through the mounting plate and is installed with a rotating plate. A gear is installed on the rotating shaft. The front wall of the groove is provided with a U-shaped mounting frame. Limiting slots are provided on the two rear sides; the fire alarm is provided with gears and plug plates, and the mounting frame is fixed to the ceiling by bolts on both sides. The gears are driven to rotate in combination with the rotation of the rotating shaft. Due to the meshing of the gears and the teeth, the plug plates extend outward or contract inward as the teeth and the gears mesh. By disengaging the plug plates from the slots on the mounting frame, the mounting plate can be quickly separated from the mounting frame, and then the alarm body can be quickly disassembled. Since the alarm is generally installed on the ceiling, the upper and lower heights cannot be flexibly adjusted, and it is impossible to carry out inspection, repair and maintenance in time. It is very inconvenient for the elderly, disabled people and pregnant women with limited mobility, and there are certain risks, so it needs to be improved. Utility Model Content

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1

[0024] See also Figure 1-5 The utility model provides a technical solution: a liftable fire alarm, comprising a fixing seat 1, a shell 2 is fixedly installed on the bottom surface of the fixing seat 1, a motor 3 is fixedly installed on the surface of the shell 2, a rotating rod 4 is fixedly installed on the output end of the motor 3, a connecting belt 5 is fixedly installed on the surface of the rotating rod 4, a notch 6 is provided at the bottom of the shell 2, a connecting seat 7 is fixedly installed on the bottom end of the connecting belt 5, a mounting seat 8 is fixedly installed on the bottom surface of the connecting seat 7, an alarm body 9 is fixedly installed on the bottom surface of the mounting seat 8, a fixing ring 10 is fixedly installed on the bottom surface of the shell 2, and a sealing ring 11 is provided on the bottom surface of the fixing ring 10, which can improve the sealing between the shell 2 and the connecting seat 7 and prevent debris from affecting the use of the spring 13 and the deviation correction block 12. 2 is slidably connected with a correction block 12, which is located on both sides of the notch 6. A spring 13 is fixedly installed between the fixing ring 10 and the correction block 12, and the spring 13 is symmetrically distributed on the surface of the correction block 12, which can improve the stability of the correction block 12 on the surface of the shell 2, so that it can steadily level the connecting belt 5. The length of the correction block 12 is greater than the length of the notch 6, and the surface of the correction block 12 is set to be rounded, which can avoid friction between the connecting belt 5 and the correction block 12, affecting the service life of the connecting belt 5. A positioning hole 14 is opened on the bottom surface of the shell 2, and a positioning column 15 is fixedly installed on the surface of the connecting seat 7, which can improve the docking stability between the connecting seat 7 and the shell 2 and prevent them from positional displacement.

[0025] Embodiment 2

[0026] See also Figure 4-5 A bolt 17 is inserted into the bottom surface of the mounting seat 8, and a column 18 is fixedly installed on the surface of the connecting seat 7. Screw holes 19 are opened inside the column 18, and the columns 18 are symmetrically distributed on the surface of the connecting seat 7, which can facilitate personnel to disassemble and assemble the connecting seat 7 and the mounting seat 8. A round sleeve 16 is fixedly installed on the surface of the mounting seat 8, and the bolt 17 is inside the round sleeve 16. The diameter of the round sleeve 16 is larger than the diameter of the column 18. The round sleeve 16 cooperates with the column 18, so that the mounting seat 8 and the connecting seat 7 can be limited, thereby improving the convenience of disassembly and assembly of the mounting seat 8 and the connecting seat 7.

[0027] Working principle: When the fire alarm is installed on the ceiling through the fixing seat 1, by starting the motor 3, the output end of the motor 3 drives the rotating rod 4 to rotate. During the rotation of the rotating rod 4, the connecting belt 5 wrapped around the rotating rod 4 is loosened. Under the action of gravity, the connecting seat 7, the mounting seat 8 and the alarm body 9 move downward, and then the fire alarm can be dropped from the ceiling, so that personnel can maintain and replace the fire alarm. When resetting the fire alarm, the motor 3 is reversed, and the connecting belt 5 is rewound around the rotating rod 4 to fix the fire alarm on the ceiling. When the connecting belt 5 slides in the groove 6, the connecting belt 5 shakes, so that the connecting belt 5 and the correction block 12 are squeezed. The correction block 12 squeezes the spring 13, so that under the elastic force of the spring 13, the correction block 12 can always flatten the connecting belt 5, thereby avoiding the phenomenon of wrinkles on the connecting belt 5. Since the surface of the correction block 12 is set to be rounded, friction between the connecting belt 5 and the correction block 12 can be avoided, which affects the connection belt 5, by arranging a fixing ring 10 and a sealing ring 11 between the connecting seat 7 and the shell 2, the sealing performance between the connecting seat 7 and the shell 2 can be improved. When the connecting seat 7 and the shell 2 are fitted, the connecting seat 7 and the fixing ring 10 are tightly fitted, so that the positioning column 15 can be inserted into the inside of the positioning hole 14, so that the connecting seat 7 and the shell 2 can be stably docked without position deviation. Under the action of the sealing ring 11, external debris can be prevented from affecting the use of the connecting belt 5 and the correction block 12. When the alarm body 9 is lowered to a suitable position, by loosening the bolt 17 from the screw hole 19, it is convenient for personnel to separate the connecting seat 7 from the mounting seat 8, so that personnel can quickly disassemble and assemble the fire alarm. By installing the round sleeve 16 on the surface of the mounting seat 8, during the installation process of the mounting seat 8 and the connecting seat 7, the round sleeve 16 can be inserted on the surface of the column 18, avoiding position deviation between the mounting seat 8 and the connecting seat 7, affecting the installation efficiency of the fire alarm, and improving the installation convenience of the fire alarm.
